Imiba yokulungiselela phambi kokugcinwa kwevalve yebhola yobhedu

Emva kobheduIvalve yeBhola yobhedu FNPTayiphumelelanga, ngokuqhelekileyo ifuna ukuchithwa kwaye ilungiswe.Umvelisi wevalve yeYuhuan ulandelayo uyakukuchazela ngamalungiselelo phambi kokulungiswa kwevalve yebhola.

ivalve

Xa ivalve yebhola ivaliwe, kusekho ulwelo oluphantsi koxinzelelo ngaphakathi kumzimba wevalve, ngoko ke ngaphambi kokugcinwa, kufuneka ukhulule uxinzelelo lombhobho kwaye wenze ivalve kwindawo evulekileyo, emva koko uqhawule amandla okanye umthombo womoya, qhawula i-actuator ukusuka. isibiyeli, kwaye emva koko ujonge ivalve yebhola Ukuba umbhobho ongezantsi womlambo ukhululwe na kuxinzelelo phambi kokuba uqhawuke kwaye uqhawukelwe kulondolozo.

Emva kokuba i-valve yebhola ihlanjululwe, kufuneka ifakwe kwaye icwangciswe emva kokuba i-agent yokucoca eludongeni ihlanjwe ichithwe ngokupheleleyo, kodwa ayikwazi ukubekwa apho ixesha elide, ngaphandle koko iya kugqwala kwaye ihlanganiswe ngothuli.Enyanisweni, amacandelo amatsha e-valve yebhola kufuneka ahlambuluke ngaphambi kokufakwa kunye nokucwangciswa, kwaye kufuneka afakwe igrisi.Igrisi yokuthambisa kufuneka idityaniswe nesixhobo sesinyithi sevalve yebhola, iinxalenye zerabha, iinxalenye zeplastiki kunye nesixhobo semidiya esisebenzayo.Xa indawo yokusebenza iyigesi, umzekelo, igrisi ekhethekileyo ye-221 ingasetyenziswa.

Gcoba umaleko omncinci wegrisi kwi-contour ye-groove yokufaka itywina.Umphezulu wokutywina wesiqu sevalve yevalve yebhola kunye nomphezulu wokukhuhlana odibanayo kufuneka ugqunywe ngegrisi.
